Awesome vid. Can't believe I haven't seen that. Thankfully due to the nature of my big Holset I dont full spool until 3200 so off the line traction is a non issue. Hell my 60' times are 2.4 :-( I can't wait to see what happens after 16gpm of methanol goes down the hatch.

It seems that drag radials would prob a better idea than 4wd launches.

 

Fact of life in racing things break.

On your transfer case it all depends on who built it.

I know your not putting out high horse power but what parts were used in the internals can make a big difference.

I would go with Drag Slicks over 4 wheel drive launches .

Unless you want to get really good at changing transmissions and T cases

The weakest link will fail first but you no doubt know that.

Good luck

 

the taco barely spins the tires dumping the clutch, i don't see the need to worry about traction with an auto.

he is pulling a fair amount of HP and hooks up imo

 

I don't know man, I think I see the front wheels spinning on launch...

Edit for clarification: meaning he's launching in 4wd. Although it's probably newer chain drive case?

 

front "wheel" spinning. It looks like the diffs are open/open. Which would make the truck still grab with just one wheel in the front. What is the reason for not getting a full spool for the rear of your truck? If you are actually trying to go somewhere in a straight line, full spool is the way to go.

BTW-- I had a supercharged taco with every possible mod on it. When I switched to 12" wide street tires in the rear and an ACT clutch, the truck hooked up nice. Well, I also had a custom TRD posi trac in the rear as well so I'm sure that helped.

 

I think you missed the point of this thread. I'm aware how open diffs behave. That wasn't the point. Also I have a LockRite rear. Zero traction issues, yet.

 

To take care of the spooling issues... 2 step!

 

Would a 2 step still work well in a rear mount configuration I wonder?

 

I would imagine so. Or hold the brake and give it some gas to spool, they call they "Powerbraking". Its only for a few seconds so it shouldn't cause any problems if everything is in good shape.

Edit: I read your turbo thread, I see you're quite experienced powerbraking. I don't know if it would help in your case, since it seems like maybe the turbo is a hair too large. Once you're off the two step, you would probably just drop boost again until the RPMs pick up.

 

If you have already tried it, tell me if it works well I have a 700hp suzuki samurai 1.8l turbo methanol project for 300ft sand drag with transmission r150f.saludos desde P.R.
